Runtime error #15

Closed chozelinek closed 1 year ago

chozelinek commented 1 year ago

I'm working with a Macbook Pro, Intel, python 3.9.11, using MacOS Ventura. I've followed the instructions in the readme to install the dependencies. I'm just trying to run the first example in a python script like this:

import holmes_extractor as holmes
manager = holmes.Manager("en_core_web_trf", number_of_workers=1)
manager.register_search_phrase('A big dog chases a cat')
manager.start_chatbot_mode_console()

I get the following traceback:

        This probably means that you are not using fork to start your
        child processes and you have forgotten to use the proper idiom
        in the main module:

            if __name__ == '__main__':
                freeze_support()
                ...

        The "freeze_support()" line can be omitted if the program
        is not going to be frozen to produce an executable.

The advice in the stack trace refers to your script rather than to the library. I reproduced the problem on my own Mac and solved it by replacing your code with

 if __name__ == '__main__':
    import holmes_extractor as holmes
    manager = holmes.Manager("en_core_web_trf", number_of_workers=1)
    manager.register_search_phrase('A big dog chases a cat')
    manager.start_chatbot_mode_console()
